Butenes were prepd. by dimerization of C2H4 in the presence of a homogeneous catalyst based on Pd2+ salt. The process was improved by using as a homogeneous catalyst an aq. acid soln. of Pd salts with anions (that form no complexes or form weak complexes with Pd), e.g., sulfate, perchlorate, phosphate, acetate, oxalate at 0.1-50 atm and 0-80°. A further improvement used strong mineral acids, e.g., HClO4, H3PO4 or H2SO4, which form no complexes or form weak complexes with Pd(II).
